Padres 2, Nationals 1

Alexi Amarista broke a 1-1 tie in the eighth when he scored from second base on Everth Cabreraâs one-out single to center field off Jordan Zimmermann (7-2), who allowed two runs with no walks over eight innings.

Alonso gave the Padres an early lead with his solo blast in the second, his fifth of the season. Stults (4-3) had a no-hitter through five innings before Kurt Suzuki led off the sixth with a single and later scored on Steve Lombardozziâs two-out RBI single.

Stults gave up one run on four hits on 89 pitches over eight innings in his longest outing since May 9, 2009. Padres closer Huston Street, who allowed a pinch-hit homer to Chad Tracy in the 10th inning of Fridayâs 6-5 loss, worked around two walks in the ninth for his 10th save.

Cabrera and Alonso had two hits apiece for the Padres, who won for the third time in their last 11 games against the Nationals. Adam LaRoche went 1-for-3 and extended his hitting streak to 15 games for Washington, which was held to four hits.
